T0 ali whom may concern: t Be it knows that i, JOHN E PITZ, a citi- State of New York, have invented new and' useful improvements Tory/ers, the foliowiiig is a specicetion.

The generei object of invention is to improve the constnlctiony of the tips of twyersa such es are asedio cormection with automatic stokers, in point of cheapness of manufacture, Weight and assembiing prop er'ties. nd tol-this end the invention re sides in orming shecover of the twyer in sections each including e phiraiity o tips, adapting each section' twyer on' which it bears, to interlock one with the other, whereby, to 'effect the positioning or the whole number ci nozzies in the section by the ect ci connecting the section itself to t-oe part upon whic'n it beers,

Other objects will. appear endrbe better understood from that embodiment of my invention of which the foiiowing is e specio" which vficotioii, reference being had to the accompanying drawings forming part thereof, in Whichz Figure l' is e sectionei deeii o a. conv-eriu tional form of automatic Stoker showing my device in side elevation and in Fig: 2 is a .date-ii section of the components of the detaii perspective of s motion of tips ojr the outer component'of the cover. Fig: 4 is e View simiier to Fig. 3 of the inner component of the cover.

n the drawings a indicates the teoie, b

the reciprocating piunger and c-o the damper rods of conventione form of entomatic s/toker. Inasmuch as the arrangement or construction of these eiements does not -v form tiie subject metter of the present epor other suitable piicetion, further description is deemed un'- necessalry. A o! d indicates the twyer shown, disposed in the ordinary manner to one side of the plunger b, Where a piiireiity of such piungers Z1 iced devices, ore empioyed and arranged as usual, in spaced relation, the twyers of course, will oe as usual disposed in their proper relation, that is Vto say, between adjacent feed devices.

The body 5 of the twyer is formed in the usual. trough-shaped structure and connects at its upper end as usual, with a source of air supply.

and the port oi the ce wested'eith ti end f r ode up oi the meer component and tire outer com ponent g. The ietter from theeterior ore sents the seme appearance es does the ordinary series o' tips nos' in use with e certain ciass of strikers; tiiot is to soy, the tips eppeor es indiidiioi snit-s whereas, eslsiiown y m Figs. 2 end 3 chess are incioded in sections one or which isL shown Fis. i), ond indicated by fr. The section has 'shown in sigg. e :me s, is' Casting, eux; s :sito bei nndeistood such section may oe fdr-ined in any other desireiie manner, The ad Vantage had, in forming ijle herein indicated by 6, in e section sucio es is shown by 7L, over the heretofore einpioyed method of formi .g the tips singiy, resides in this: The section is lighter in weight tiren Wouid oe s corresponding number o individuei tips. This diierence in weight is brought about oy forming the tips substentieiiy rif-shaped in contour, giierebyrendering es unnecessary the solid rectanguer elongation or bose which would extend to the right of the ex;- treme tip on the rignt in Fig. S, to form a support for e succeeding tip7 if such tip on the extreme right ir; Fig. 3 were cost singly. This is of greet imperi-ence since, is Weil known, these tips succumb to the action of fire in e Yreietively short time that when it becomes necesseojrto scrap the cps, which is done when the' point one or more tips is burned wey5 e less :insonne of metal Wili e @resem structure than Where the tips ere imiiidoaiu Then egein, with tire individcoi tip each roest ce formed with aiocirinef ineens' to interiocir with the tio on wi ich it beers and moreover5 the seiferei tipsmeking up the cover must be seperately Tiendied to eiiect essembiing of the cover. i itir the present strncture,'i1ow ever, it "siii 1oe observed that time handling and adjusting into position taining, gior ins-rence; sin tips, requires no 4more time than does the neiidiing oi the present yp-e of indivi@ i tio it rviii of course-be understood that the sections may oe formed with any desirable number of tips that sniiicient sections Wiil `oe provided and proportioned in iength so es to form cover for the body .5 when arranged end to end, es shown. The sections may be estened to eine 4body 5 in any approved manner. En thedrewings The correr herein 'disidente L eeneraiy 'bv sov of e section con meting the sections to the body. In thishave shown an ideal :u'rngelnentin the term of the inner component f for con- ;iimnvement the said inner componenti( is uitub'lv fastened to the sides of the bo y 5 his lmeans of suitable fastening devices` 4which pass through openings in lugs 7 depending from the sides 8 offthe component fr This said component f is formed with-f1 top 9 V-shziped in cross section to conform to thecross sectional contours of the sections It, whose opposite' sides are provided with anglihu-ly disposed .elongated ports 10 #which register with the ports or openings.

1l. in the front faces of the tips 6 which latter are disposed so as to direct the blast forwardly from the tips, additional outlets or ports 12 being provided on opposite sides of the points of ythe tips and disposed so as to direct the blast in the same direction as .do the ports l1. The middle portion of the top of thc component f has slots 1,3 which take suitablev fastening means in 'Eueform of hooks 14-14 depending from the opposite end portions' of the sections L. lfVith wthis construction it will bel obvious that the several sections may be removed successively by moving the upper longitudinally of the twyer until the hooks 14 become disengaged and permit the lifting of the section from the component f.

What is claimed as new is:

1 In n twyer a section V-shaped in transverse section and having at itsupper side a plurality of tips provided with openings,

said section being provided at its underside with integral hooks the pointed ends of y vV-sheped con guration of the 'section et the opposite sides of said laneA being of equal magnitude, the ends ogthe said hooks terminating short "of the plane vin which ,the side edges of the V-shaJ d'lsection lie,

In testimony whereo I aliix my signature in presence of two witnesses.
